This study is to find the dynamic properties of concrete materials under both high strain-
rates and triaxial stress states and to formulate the dynamic constitutive model of concrete.
Thus, triaxial rapid compressive loading tests for concrete specimens were executed. In tests,
the compressive strength of concrete, the confining pressure and the loading rates were
chosen as test parameters. Based on test results, the influence of these parameters on the
mechanical properties of concrete are examined, and then the constitutive model of concrete
with the strain-rate effects is proposed.
